That’s how I lost a lot of weight- intermittent fasting plus diet modification.
IOW, don’t eat so damn much.

Ceasing ‘dinner’ as a full meal 95% of the month was a big deal for me.
Frankly, I don’t see it discussed much.
I try to coordinate my ‘fasting’ with busy days - usually projects at home - which distract from my stomach.
Works like a charm.
Side note: In the hours since I first saw the OP article, my memory suggests that they came out with some ‘expanding’ food article decades ago to serve the same purpose. I did a quick search and didn’t find anything, but my memory also suggests the product was a commercial failure.
Seriously: Who by now hasn’t heard of chia seeds?
